Rice Krispie Treats were a staple in my house when my kids were growing up. Now, when I want just one, I make this single serve Rice Krispie Treat in the microwave. It has the same buttery, marshmallowy goodness but in a perfectly portioned size. It’s quick, easy, and made with just a few ingredients. I use a small dish, but a mug or any small bowl works too.

How To Make A Single Serve Rice Krispie Treat
See the recipe box below for ingredient amounts and full recipe instructions.
To make a single Rice Krispie Treat, start by melting butter and marshmallows together in the microwave until soft and smooth. Stir in the crispy rice cereal, making sure it’s fully coated in the marshmallow mixture. Press the mixture into a buttered dish, spreading it evenly, then let it cool before enjoying.
No Microwave?
Melt the butter and marshmallows in a small saucepan over low heat, stirring until smooth. Then mix in the cereal and press into a dish as usual.
Expert Tips
- Avoid Overheating: Remove marshmallows from the microwave as soon as they melt to keep them soft and easy to mix.
- Stir Gently: Mix lightly to keep the cereal crisp.
- Press Lightly: Avoid packing too firmly for a soft, chewy texture.
Frequently Asked Questions
Yes. Double the ingredients and use a larger dish. You may need to microwave the marshmallows a few seconds longer to fully melt them.

You forgot to double the regular marshmallows when doubling recipe – thanks for this recipe- I’m 80 and until a few weeks ago had never made rice crispy treats! Glad to have this small batch recipe.
To make it a salty – sweet treat substitute 1cup of RUFFLE Potato chips crushed to bite size instead of the Rice Krispies.
Delicious! Quick and easy to make!
Thank you!
I line my dish with buttered plastic wrap, a quick pull and it’s out and ready to cut.
